LOOSE-LEAF BINDER.

Application led March '1, 1924. Serial No. 696,219.

To @7l @7mm may concern.'

Bc it known that l, Hmmm AUBURN, a citizen of the United States of America, and a resident of Mount Healthy, in the county of Hamilton and State of Chio, have invented a new and useful Improvement in a Loose-Leaf Binder, of which the following is a specification.

nobject of my invention is to provide a simple and etlicient binder that will dispense with locking keys and the like, employed heretofore.

ift-mother object of my invention is to prov'de a device having a minimum of parts and wherein the parts are so related that same will not readily fail of their intended functions.

rthese and other objects are obtained by means described herein and disclosed in the accompanying drawings, in which:

Fig. 1 is a perspective view of a loose leaf binder having associated therewith means en'ibodying` my invention.

Fig. 2 is sectional view on line 2v2 of Fig. 1.

Fig. 3 is a perspective view of a locking plate forming a detail of my invention.

TEig. 4 is a View of a locking dog forming a detail of my invention.

Fig. 5 is an enlarged fragmental sectional view showing the parts of locking device in locked and unlocked positions, all of which form details of my invention.

The device o; yny invention comprises the conventional base cover G iixedly carrying posts 7 and 3. The posts 7 and S may be made sectional is common whereby same inav be iideini ely extended in length. A movable cover 9 carries means 'for adjustably securing said movable cover upon the posts 7 and 8 carried by the hase or relatively tixed cover. Said means comprises a tubular housing 10 one end of which may be closed by any suitable plug 11 andthe other end of which contains a reciprocating' plug or finger piece 12. A reciprocating plate 13 is fixed to the linger piece 12 and is disposed vithin the chamber 141 formed within the tubular housing 10. The plate 13 has a central perforation 15 through which extends a, rivet or stud 16 for limiting the movement of the reciprocating plate 13. At both sides of the aperture 15 there are formed ways 17 and 18 in the reciprocating plate through which the posts 7 and S may extend. The ways may be in the nature of apertures as shown at 17 or may be slots as shown at 18. Adjacent 4the ways 17 andlS, the reciprocating plate is developed into upwardly extending inclined lugs 19 that cooperate with locking dogs 20 in a manner that will be explained hereafter. The housing 10 is provided with an'inwardly extending boss or protuberance 21 that has a yieldingaction in resisting movement of the finger piece 12, and such protuberance is adapted to lodge in a recess 22 provided in the linger piece 12 whereby to preclude lateral vibration as well as longitudinal displacement of the finger piece 12 when the parts `are in the relation shown in Fi 2. A dog is provided for cooperating with the reciprocating` plate 13 at each of the ways 17 and 18. rPhe dogs are of an L-shape, the shorter leg` 26 thereof being provided with lugs 23 and 24 thatstraddle the reciprocating plate and lodge in apertures 25 provided in the housing 10 thereby limiting the move-ment of the dog longitudinally of the housing. This is merely a common expedient for preeluding shifting of the dogs within the reciprocating plate and other means for effecting this may be Vernployed. The longer leg 27 carries a spring that engages the inner wall of the casing 10 and urges the free end of the longer leg 27 toward the reciprocating plate 13. The said 'free end of the longer leg 27 is ydisposed adjacent the inclined lugs 19. Reciprocation of the plate 13 serves to pivotally move the free ends of the dogs, about the engageineut of the lugs 23 and 2st upon the walls of the opening` 25 against the yielding resistance of the spring 28. Each dog is provided with an aperture 29 that is slightly larger in diameter than the cross section of the posts 7 and 8 and through which apertures such posts extend. The cooperation of parts is such that when a dog is moved to the position shown in dotted lines in Fig. 5 the walls of the aperture 29 are spaced from the posts whereupon the loose cover' maybe moved upwardly upon the posts and may be removed from the posts. lVhen the dog is moved to the position shown in full line of Fig. 5, the walls of the aperture 29 engage the post at opposite places and thereby effect a binding action upon the post that precludes upward movement of the movable binder or cover 9 yet which will permit the downwardl movement of the movable binder section upon the post. The housing 10 is provided with suitable apertures and 31 through noY which the posts may extend. The lower or fixed binder section may be provided with a easing 32 that is substantially identical in shape to the housing 10 and such easings and housings may be flexibly connected with the cover boards 33 and 34 of the binder.

W'hat I claim is:

In a binder of the class described the conibination With a` tubular housing having an open end and a sealed end, of a locking de- Vice contained Within the housing, an actuating plate for the looking device contained Within the housing and having its one end reciprocable through the open end `of the housing, and a flanged finger pieoe'earried by the last mentioned end of the actuating plate and adapted to enter the opening in the housing With its fianged portion in abutment With the open end of the housing.

Intestimony `whereof, I have hereunto subscribed my naine this 19th day of February, 1924.

HUBERT AUBURN.
